NOVELTY - Synthesizing graphene in-situ nucleation lithium iron phosphate comprises (i) taking iron(ii) hydroxide and reduction agent, (ii) taking phosphoric acid, lithium hydroxide and graphene oxide, adding deoxygenated water, ultrasonically oscillating, evenly dispersing to form modified graphene oxide suspension, (iii) adding iron(ii) hydroxide and reduction agent to the modified graphene oxide suspension, and stirring evenly to obtain mixed solution, and (iv) adding the resulting mixed solution in a reaction kettle, stirring, introducing inert gas, heating, cooling, filtering, and drying. USE - The method is useful for synthesizing graphene in-situ nucleation lithium iron phosphate (claimed). ADVANTAGE - The lithium iron phosphate has excellent discharge performance at 20-50 degrees C. DETAILED DESCRIPTION - Synthesizing graphene in-situ nucleation lithium iron phosphate comprises (i) taking iron(ii) hydroxide and reduction agent, (ii) taking phosphoric acid, lithium hydroxide and graphene oxide, adding deoxygenated water, ultrasonically oscillating, evenly dispersing to form modified graphene oxide suspension, where mol ratio of iron, phosphorus and lithium is 1:1:1:4, and the addition amount of the graphene oxide is 0.5-5% of the iron(ii) hydroxide, (iii) adding iron(ii) hydroxide and reduction agent to the modified graphene oxide suspension, and stirring evenly to obtain mixed solution, and (iv) adding the resulting mixed solution in a reaction kettle, stirring along the edges, introducing inert gas, heating and preserving heat, cooling to room temperature, filtering, and drying.
